The function broncolor HS lets you use now flash in combination with very short exposure time settings on your camera. For example, with ambient light, even with the aperture wide open (selective focus), the image can be underexposed correctly with up to 1/8000 s and Siros L still lets you set dominant and creative light effects.
As from now on broncolor HS is also available for Siros L and Move. All you need for this, is the RFS 2.2 transmitter, which is available for Nikon, Canon or Sony cameras. In addition, “HS” must be activated on all flash unit in use. This modifies the flash curve and guarantees, in combination with RFS 2.2, correct exposure with no limits on your choice of shutter speed.
A change of the flash tube is not necessary, neither with Move nor with Siros L. For Siros L units we recommend a software update to version 52.04. This update improves the HS function and may be downloaded from our website: http://www.bron.ch/sirosfirmwareupdate/.
However, for Move a software update is required. This update must be made at the aftersales service point's. Further, please note that HS for Move is optimized for the use with one lamp. If working with two lamps only a symmetric power distribution is possible.

Introduction of the new RFS 2.2 transceiver
The RFS 2.2 transceiver operates as a remote control or radio flash trigger for one or more broncolor power packs or monolights equipped with an RFS 2 interface. Power packs or monolights not equipped with an RFS 2 interface can be operated by connecting an RFS 2.2 transceiver (as a receiver).

RFS 2.2 as transmitter
RFS 2.2 is available for Canon, Nikon or Sony and optimized for its operation. Based on the specific construction of the hot shoe for these camera systems, the use with other brands is not recommended or needs to be tested first.
RFS 2.2 as HS transmitter
In the HS mode the transmitter is factory set to work correctly with all camera models of Nikon, Sony or Canon. The time between flash triggering and shutter opening is controlled by a prepro-grammed trigger delay in that way that optimum lighting results with an exposure time of up to 1/8000 s may be achieved.
When HS is active, you can choose through the HSMA menu (HS Manual Adjust) the optimal exposure depending on the camera model. The purpose of HSMA mode is to override the automatic HS flash trigger.
